| Zusammenfassung: | The invention discloses a waveguide display system and a display device. The waveguide display system comprises a first waveguide sheet and a second waveguide sheet, the first waveguide sheet comprises a first coupling-in unit, the second waveguide sheet comprises a second coupling-in unit, and the first coupling-in unit and the second coupling-in unit are located on the same side; the first coupling-in unit is used for coupling light to the first waveguide sheet, one part of the light enters the first waveguide sheet for transmission after being totally reflected in the first waveguide sheet, the other part of the light is reflected and refracted to form reflected light and refracted light, and the refracted light enters the second coupling-in unit through the lower surface of the first waveguide sheet; the second coupling-in unit is used for coupling the refracted light to the second waveguide sheet, and the refracted light enters the second waveguide sheet to be transmitted after being totally reflected in |
